Circular light bulbs, often referred to as circular fluorescent lamps, operate on the same principles as traditional linear fluorescent lamps but are designed in a circular shape for aesthetic and practical purposes. These bulbs consist of a glass tube coated on the inside with phosphor and filled with a low-pressure mercury vapor and inert gases like argon or krypton. When the bulb is turned on, an electrical current flows through the electrodes at each end of the tube, creating an electric arc through the gas. This arc excites the mercury vapor, causing it to emit ultraviolet (UV) light. The phosphor coating on the inside of the tube absorbs this UV light and re-emits it as visible light, producing the illumination we see. Circular fluorescent bulbs require a ballast to regulate the current and provide the necessary voltage to start the lamp. The ballast can be either magnetic or electronic, with electronic ballasts being more energy-efficient and providing instant start-up without flickering. The circular design allows for even light distribution and is often used in fixtures where space is limited or where a uniform light source is desired, such as in ceiling fixtures, desk lamps, or decorative lighting. The shape also helps in reducing shadows and providing a more diffused light, making it suitable for various applications. Overall, circular fluorescent bulbs are valued for their energy efficiency, long lifespan, and ability to produce a soft, even light, making them a popular choice in both residential and commercial settings.
